All NativeRawSymbols will have a unique symbol ID (retrievable via getSymIndexId). For now, these are initialized to 0, but soon the NativeSession will be responsible for creating the raw symbols, and it will assign unique IDs. The symbol cache in the NativeSession will also require the ability to clone raw symbols, so I've provided implementations for that as well. llvm-svn: 306042
